A patch provide a interface to limit total page cache in /proc/sys/vm/pagecache_ratio. The default value is 90 percent. Any feedback is appreciated.
[snip] wakeup_kswapd and shrink_all_memory use swappiness to determine what to reclaim (mapped pages or page cache). This patch does not ensure that only page cache is reclaimed/limited. If the swappiness value is high, mapped pages will be hit. One could get similar functionality by implementing resource management. Resource management splits tasks into groups and does management of resources for the groups rather than the whole system. Such a facility will come with a resource controller for memory (split into finer grain rss/page cache/mlock'ed memory, etc), one for cpu, etc. Balbir - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
